Comment: The camera picks on some silky structure in this Montana sapphire but it is not visible to the eye (and no, we still don't edit our images with photoshop as you can see). Precision cut untreated US sapphire in full size. Nice to see the color play in this sparkler, it moves throughout the stone from a lake green to a sky blue and back. Not your every-day sapphire but a unique piece of nature masterfully crafted and displayed. See side image for an idea on how precise such a cut is.
